AMX-9CX4

The preamp mixer AMX-9CX4 is a professional digital automatic preamplifier with a 5" front display, DSP digital signal processor and excellent sound qualities.

The digital automatic preamplifier is equipped with 8 universal inputs on XLR (MIC / LINE by DIP switch), 10 input PEQ and 5 output PEQ, audio matrix, feedback limiter, 3 digital frequency shifters with output select, 3 PRESETS, SD / USB player with BT receiver (for direct connection with Bluetooth-enabled devices) and more.

The AMX-9CX4 pre-amp comes with further most modern technologies such as a built-in digital de-esser for dynamic attenuation of unwanted "ess" and sibilant sounds and a compressor / expander / limiter function for dynamic processing of audio signals and recordings.

NEW! AMX-"CX" series now with large 5" front display and innovative technical features:

By redesigning the front panel, Phoenix Professional Audio's AMX digital automatic preamplifiers have not only received a "face lift" – the new models now enable direct programming on the large 5" front display using the SETTINGS ENTER button. This makes setting the numerous parameters even more intuitive and easier.

The AMX-CX series is also full of technical innovations:

The new automatic pre-amps are equipped with three digital frequency shifters as a feedback lock with output select for outputs 1, 2 and 3. If necessary, three outputs can now be programmed with digital frequency shifters at the same time. The new series also has a digital de-esser with BYPASS function.

The integrated BT system (connection via Bluetooth-enabled devices) has been supplemented with a powerful external antenna and a security function, which now enables BT Pair with password protection.

Other new features include the SD / USB player with title display and three PRESETS P1 / P2 / P3 with a selection button on the front.

The AMX-9CX4 automatic preamplifier is designed for professional PA applications in acoustically challenging rooms (building acoustics), such as churches and cathedrals, and is used where most other devices do not produce a positive outcome or an entire rack of system components would have to be built to provide a reasonable acoustical result.

The 8 universal inputs can be switched between MIC and LINE sensitivity by DIP switches. Each of the 8 universal inputs has switchable phantom power and an HPF filter (100 Hz).

The universal inputs are equipped with a switchable automatic microphone system - DIGITAL SIGNAL DELAY FIELD (DSDF). Only microphones being addressed are automatically activated and are controlled and monitored by the processor system (DSDF). Unnecessary open microphone channels are closed.

Through the input matrix (DIP switch), all 8 input channels can be assigned to the MAINSUM-1 DSP outputs 1 to 3 and MAINSUM-2 to the DSP outputs 1 to 3 and 4.

The built-in MP3 player module with BT receiver (including IR remote control) has inputs for USB sticks and a SD memory card and will optimally accompany you during the operation. The integrated BT receiver supports all common Bluetooth-enabled devices and allows you to wirelessly transfer music or pre-made texts from your mobile phone, PC or MP3 player to the amplifier and play it.

All settings of the matrix, the DSDF system, priority or conference programming can be found in the device manual.
